CENTRIFUGAL-SEPARATOR LINER.

SPECIFICATION forming part of Letters Patent No. 635,579, dated October24, 1899.

Application filed Tune 28, 1899. Serial No. 722,136. (No model.)

T0 or whom, it may concern:

Be it known that I, JoHANN DIEDRIOH GEORG OHLHAVER, of Hamburg, Germany,have invented a new and useful Improvement in Liners for CentrifugalSeparators, of which the following is a specification.

In centrifugal cream-separators the separation is effected in a radialdirection. In all bowl-liners for centrifugal cream-separators it hastherefore been considered that the separation is most favorably effectedwhen the milk to be separated is divided into thin layers in such a Waythat a radius drawn from the axis to the periphery of the bowlintersects as many of such layers as possible in order to shorten thepath of the separation, and for this reason conical, cylindrical,prismatic, spiral, or the like partitions have been proposed forinsertion. In my improved liner, on .the contrary, the milk is notdivided radially into layers. Experience has shown that the separationis most favorably effected when the angular velocity of the bowl israpidly imparted to the milk, when the currents in the bowl are suitablydiminished,and when the vibrations of the liquid are removed as far aspossible. My improved liner completely fulfils these conditions.

.. It consists of perforated, cut, or punched therefore to beperforated,out, punched, or otherwise provided with holes a or must consist ofsieves with close meshes. It is of advantage to provide the outer edgeof the horizontal partitions with a narrow vertical rim 0. It is notnecessary that the radially-extending projectionsb stand at right anglesto the horizontal partitions a, as they may form any suitable angle withsaid horizontal disks. The radially-arranged projections 11 may bemounted directly on the horizontal sieves or perforated, cut, or punchedhorizontal plates a, or these projections may form separateradially-arranged vertical disks. projections b may also be continuouswalls running from top to b0ttom,in which the horizontal sieves orperforated, out, or punched disks to are inserted.

A form of construction of the liner is shown in Figures 1 and 2 of theaccompanying drawings in vertical section and plan.

The form of construction is arranged in each case to suit the actualcircumstances.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- In a liner for the rotating bowl of a centrifugalseparator, the combination with the perforated horizontal. partitions,a, narrow vertical rims c, and vertical partitions 5, sub-- stantiallyas herein shown and described.
